ABSTRACT:
A method and appartus are disclosed for making a subsea flowline connection between two pipelines. A connector assembly having a base plate is positioned on the sea floor to receive the ends of two intersecting pipelines. Once one of the pipelines is attached to the base plate, the base plate is displaced horizontally along the sea floor toward the other pipeline. When the second pipeline is attached to the base plate, the ends of the pipelines are a predetermined distance apart and a prefabricated spool piece is then remotely installed. In this manner, the base plate permits the connection of spatial and axial misalignments which otherwise would require the on-site fabrication and installation of a spool piece.
